北极熊生活在北极，北极大陆是一块巨大的冰在地球上。北极熊是熊科熊属的一种动物，是世界上最大的陆地食肉动物，它又名白熊。北极熊的大脚掌使得它可以用前脚掌当”桨“，在水中游泳，而宽大的后脚掌则用于在冰面上和雪地里行走；嗅觉极其灵敏，可以捕捉到方圆1公里或冰雪下1米的气味。但由于人类造成的全球性变暖，也就是“温室效应”，导致北极冰盖融化。北极熊即将失去它赖以生存的家园。为了这些处于危险中的动物，也为了人类自己，不要破坏环境了。
Polar bears live in the Arctic. The Arctic continent is a huge piece of ice on the earth. Polar bear is a kind of bear in Ursidae. It is the largest land carnivore in the world. It is also called white bear. The polar bear's big paw enables it to use the front paw as a "paddle" to swim in the water, while the wide back paw is used to walk on the ice and in the snow; the sense of smell is extremely sensitive, which can capture the smell of a kilometer around or one meter under the ice and snow. However, due to the global warming caused by human beings, namely the "greenhouse effect", the Arctic ice sheet melts. The polar bear is about to lose its home. For the sake of these animals in danger and for the sake of human beings, don't destroy the environment.
The environmental movement has marked its advancement in a series of caps and cutoffs and deadlines. On Jan. 9, one of those targets came and went: the Fish and Wildlife Service (FWS), the Interior Department agency that evaluates endangered species, was due that day to deliver its ruling on the polar bear. Though FWS had already taken over a year to investigate the polar bear’s plight (困境)—green groups sued(向请求) the federal government two years ago to declare the animal as threatened under the Endangered Species Act—the day before the deadline, the agency announced that it would need another month to decide, due to the complexity of the bear’s situation.That situation is as follows: as temperatures warm, the Arctic sea ice that supports the polar bear shrinks, leaving the animals to drown as they are forced to swim long distances between the ice, or simply starve to death. The summer of 2007 saw record melting of Arctic sea ice, and NASA scientists now predict that the Arctic could be ice free as soon as the summer of 2013. “Without the sea ice, there is no polar bear,” says Andrew Wetzler, director of the Natural Resource Defense Council’s endangered species project. Indeed, a study by the United States Geological Service in September 2007 projected that the polar bear population—which currently stands at roughly 25,000_—could decline two thirds by 2050.Now the bears face another threat. On Feb. 6—three days before FWS’s new deadline—the Minerals Management Service (MMS), also part of the Interior Department, plans to lease(出租) 30 million acres for oil and gas drilling in the Chukchi Sea bordering Alaska_, where one fifth of the world’s remaining polar bears live. Drilling—with the risk of spills(散落) and seismic(地震的) damage—could further jeopardize (危害) the polar bear, and environmentalists consider it suspicious that FWS decided to delay its decision until after the lease sale. “It seems that every time there is a choice between extraction and extinction in this administration_, extraction wins,” said Rep. Ed Markey, the chairman of the House Select Committee on Energy Independence and Global Warming, at a hearing on the issue held Thursday.But the fate of the polar bear goes beyond a single oil and gas project. If the species are declared threatened, FWS will have responsibilities under the Endangered Species Act to protect the bears from their main danger—in this case, climate change. That means the government could be challenged legally for anything that increases carbon dioxide emissions—like a new coal power plant—on the grounds that further climate change would further endanger the polar bear. “It would be the first time that the Bush Administration would recognize that global warming had a significant and specific impact on a living being,” says Eben Burnham Snyder, a spokesperson for Markey. “This could have a wide ranging effect on the energy and environmental policies of this country.”来源：新高考·高二语数外
